AB  - The mechanical behavior of buried HDPE double-wall corrugated pipes is mainly 
      affected by the material and the structure of the pipe wall. Here we studied a 
      peculiar material that added fly ash (FA) in high density polyethylene (HDPE) to 
      develop composites. We have conducted research on FA/HDPE composites with 
      different mix proportions. When 5% compatibilizer was added to the 10% FA 
      masterbatch/HDPE composite, the Young's Modulus of FA/HDPE composite was higher. 
      This paper mainly studies the mechanical behavior of the structure of pipe walls 
      for materials with this proportion of the ingredients. The mechanical behavior of 
      double-wall corrugated pipes with different ratios of interior and exterior wall 
      thicknesses is studied by keeping the sum of the interior and exterior wall 
      thicknesses unchanged. Pipes with six different ratios of interior and exterior 
      wall thicknesses are simulated; the results show that the strain of crest and 
      liner gradually decreased and the valley strain gradually increased with the 
      increase of the exterior wall thickness. By comparing inner and outer wall 
      thickness ratios from 0.67 to 2.33, it is found that the structural performance 
      and economic advantage for the double-wall corrugated pipes is best when the 
      thickness ratio of the interior wall and the exterior wall is controlled to be 
      from 1.3 to 1.8. This paper expounds the deformation mechanism of double-wall 
      corrugated pipes from the perspective of mechanical behavior and structural 
      characteristics, and provides a reference for material selection and structural 
      design of double-wall corrugated pipes.
